This invention relates to separable fasteners More particuiarly, the invention deals with they provision oi aV nylon or other Spring like plastic nubbin onV an end stop link whereby aV slider may be forceably moved over the Stop linkin providing a quick pull apart separation ofthe stringers as and when desired; The-novel; fea-` tures` of the invention will be .best understood. from the following description when takenv together with theaccompanying drawing, in. which certain embodiments oi the invention. are dis:- closed, and in which the Separate.A parts are. designated by suitable reference. characters. in each ofthe views, andin which:

Fig. 1 is a face View of the upper end portion of a pair of stringere, showing the Slider in section and with the parts in a normal. stop. position.

Fig. 2 is a partial sectionxon the. line 2 2 of Fig. 1 on an enlarged scale and showing only one Stringer and omitting, background illustrations; and

Fig. 3 iS a View similar to Fig. 2, showing only a part of the construction and showingl a modif cation.

In Fig. 1 ofthe drawing. I have' shown at I0 and II upper end portions of a pair of. Stringers tothe beaded edges I2 and I3 of which are attached scoops It and I5, providing normal coupling engagement of the stringers. The scoops. I4 on the Stringer Iii extend for a greater length belond the end scoop I5 of the Stringer II so that the Slider| Iii can extend to an end Stop I'I on the Stringer ID.

On the shorter Stringer IIl are provided two special links, scoops or elements I8 and I9. The link I8 forms what may betermed a stop link, and has a pair of finger portions 2t adaptedto extend between spaced scoops I4 of' the Stringer I in the manner illustrated. The Special scoop' I9 operates as a guide scoop and hasa pair of ngerszl also free to extend between thescoops I4 of the Stringer it as and when the slider I6 is forceably moved in the direction ofthe stop I'I.

Considering Fig. 2 of the drawing, it will appear that the slider I or the spaced top and bottom Walls22V and 23 thereof have'at one side recesses, asat 24 and 25. These recesses openthrough the, wide4 end26of the slider, asseeniin'Fig. 1,

and terminate at shoulder' portionsf.-21'and.28`,

the shoulder portionl 28 being indicated in Fig. l of the drawing; These shoulder portions are Short or the contractedor single clianne'iied end 29 of the slider. It will be understood that the dimensions or the recesses 2&5 and 25Y and the shoulders 2T- and 28, as appearing in Fig. 2 of the drawing, are exaggerated for Sake of clarity.

The stop link or Scoop- Is has an aperture Sii extending therethrough which also pierces the tape II or the beaded edge I3 thereof, and in this aperture is arranged a stop pin or nubbin 3| which extends slightly beyond upper and lower surfaces of the link or scoop I-8-and sufficient to enter the recesses 24 and 25A and engage the shoulders 2l and 28 to check'` normalV closing movement of the-Slider. However, by. forcing. the slider` upwardly.' as seen in. Fig'.V 1, the. pin or nubbin 3l will spring over the shoulders' 2-'I and 2a, allowing the slider to extendto the Stop I1, thus freeing the Stringer II from the slider and allowing both stringers to be quickly pulled apart.

Fasteners of the type and kind under. consideration are desirable on certain types and kinds of installations Wherey it is desirable to provide a quick Separation of the stringers, and particularly. on longstringers where time is requiredin moving a slider along the coupled scoops in Separation' of the Stringer. For example, in mounting of interlinings in coats where the interlining is held in the coat by a separable fastener, extending along the coat front and over the shoulders and at the back of the neck. With my present quick separable fastener, a lining could be removed. by Simply forcing the slider to the Stop, as at I'I, and then the lining could be quickly pulled fromk the coat avoiding the necessity of operating the Slider rst along one side, across the shoulder and neck portions and thendown the other side.

Fasteners of the type and kind under consideration are applied to what is commonly known separable fasteners, Where the other un- Shown end of the stringers have` pin and box Tor other couplings forv quick` Separation of the stringers, but as these vstructures are well known in the art, no illustration thereof isherein given. It is well to point. out,.however, thatthe slider is held against removal. from onev Stringer, for example, thestringer It.. In other words, the conventional box part ofthe coupling is applied to the Stringer Iil for this purpose.

The. pin or nubbin Si is preferably composed ofra springzlike material, an'dlihave foundthat plastic. materials are A-sultabletfor f this purpose.

nylon type of plastics being one which is suitable. The pins or nubbins may be secured to the link or scoop I8 in any desired manner, regardless of whether the fastener is metal or of a plastic type. In plastic fasteners a suitable adhesive may be employed to adhere the parts together.

In Fig. 3 of the drawing is shown a slight modication in the type of stop pin or nubbin employed. Here the special stop link or scoop I8 has apertures 32 and 33 which extend to the bead I3' of a tape Il' and two pins or nubbins 35i and 35 are employed, one tting in each of the apertures 32 and 33, and seating upon the beaded edge I3 of the tape. The pins or nubbins 3ft and 35 will be of the same type and kind as the pin or nubbin 3|.

In forming the scoops or links as die casting, the apertures as at 30 in the special link or scoop I3, and 132-33, as at I8', may be formed in the casting of the scoop and in one instance, a punch is employed to pierce the bead of the tape to form a single passage as at 30 through the link I8, whereas in the other instance, this operation 'is dispensed with and two pins or nubbins as at 34-35 are employed.

Considering Fig. 1 of the drawing, 3I represents the frog or web at the Wide end 2S of the slider, which forms the diverging channels for guiding the scoops in coupling and uncoupling of the stringers. Considering now Fig. 2 of the drawing, it will appear that the top and bottom walls 22 and 23 have inturned side flanges 3i and 3S which retain the scoops in the channelled slider body. At 39 is shown part of the loop or coupling with which the conventional pull, not shown, is attached.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
